Short summary

Tidal-water intrusions can cause warm ocean water to extend beneath grounded Antarctic ice, increasing submarine melting beyond the grounding line. Here, a new parameterization representing this effect is introduced and tested in the Yelmo ice-sheet model, revealing that tides could amplify ice loss and sea-level rise. This new parameterization shows good agreement with inferred grounding zones.
